The AGE reports (11/12/09):

International tourist numbers are dropping (with figures for the three months to September 2008 showing 40,000 fewer than in the same period in 2007).  In 2008 the economic contribution by all visitors grew by 7 per cent to $24.5 billion on the previous year (2007), although that growth was almost entirely driven by the education market which accounts for a third of the expenditure.
